Figure 2 As shown, the oblique shock-absorbing pad 5 is installed between the engine mounting bracket 4 and the mounting chassis 8 through the connecting piece 9, and the engine is damped by the oblique shock-absorbing pad 5 and fixed by the engine mounting bracket 4. During the operation of the engine, the oblique shock-absorbing pad is used for damping, and during the bumpy driving, the engine is only limited by the oblique shock-absorbing pad and the engine mounting bracket, which requires a high strength of the oblique shock-absorbing pad, and the high-strength oblique shock-absorbing pad cannot meet the shock-absorbing requirement, so the oblique shock-absorbing pad is easy to break during the transportation of the engine.

[0006] Preferably, the mounting chassis is a rectangular chassis with surrounding edges on all sides, and two mounting plates with upwardly turned edges are provided on the left and right sides of the bottom plate, and two oblique shock-absorbing pads are installed on each mounting plate.

[0007] Preferably, the engine mounting bracket is a bracket with a downwardly flanged edge, and two mounting platforms are provided on the same side of the two mounting plates corresponding to the engine mounting bracket, and the engine mounting bracket is limited by buckling the flanged edge with the mounting platform.

[0008] Preferably, the bolts are welded to the mounting platform.

[0009] Preferably, the annular shock-absorbing pad adopts a double-layer shock-absorbing pad to improve the shock-absorbing effect.

[0010] Preferably, the engine mounting bracket is fixedly connected to the engine via a boxed mounting block provided in the middle.

[0011] The beneficial effects of the utility model include: by arranging an annular shock-absorbing pad and a shock-absorbing column for shock absorption, increasing the shock-absorbing buffer spacing, improving the shock-absorbing effect, and playing a good shock-absorbing role in the vibration between the docking engine and the mounting chassis, and supporting the engine to distribute the load, while cooperating with the engine mounting bracket and the mounting chassis to protect the engine and extend the service life of the engine; by arranging the shock-absorbing column and the oblique shock-absorbing pad between the engine mounting bracket and the mounting chassis, when the engine vibrates or bumps to a large extent, the shock-absorbing column replaces the oblique shock-absorbing pad for shock absorption and limiting, reducing the oblique shock-absorbing pad from working for a long time when the engine vibrates or bumps greatly, making the oblique shock-absorbing pad used not easy to break, and improving the safety factor.
